Prognosis of Gangrene

The prognosis of gangrene depends on the type of gangrene and the overall health of the patient.

People with dry gangrene tend to have the best prognosis since it does not involve infection and spreads slowly. They may lose some local function due to tissue loss. In cases of people with an underlying condition like atherosclerosis or diabetes, there is a possibility of a recurrence.

In cases of infected gangrene the prognosis depends on various factors. If it is treated early, the possibility of recovery is good. Age too plays an important role. For diabetics, blood sugar levels play an important role in bringing the infection under control. People who have underlying conditions like compromised immune systems, diabetes and atherosclerosis and who have advanced cases of gangrene are most likely to have complications due to gangrene.

Statistics in the U.S. show a mortality rate of 6% - 7% for patients hospitalized with gangrene. This rate increases to 20% - 25% if septicemia sets in. Prompt treatment necessitates amputation of digits or limbs in only 15% - 20% of cases.
